If you want to work on computer-aided design (CAD), geometry, or graphics, you've come to the right place! Help us improve open source CAD.

Well prepared proposals from capable students have an outstanding chance of getting selected. We consider proposals for all skill levels ranging from simple to crazy hard and everything in between. Introduce yourself, and we'll help you plan one right for you.

Remember that project descriptions are just initial ideas. You must expand with considerably more detail. Change the goals to fit your experience and interests. See our checklist to get started.

This year, BRL-CAD is coordinating with five other communities that will get 1-2 students each to help bridge our work and encourage collaboration. Projects that help exchange data or share code are desired!

OpenSCAD: rich syntax, programmable geometry. Lots of possibilities to make it interoperate with BRL-CAD and LibreCAD.

This year, we are most interested in topics that will immediately benefit BRL-CAD users. Please align your proposal with one of the following three focus areas. Talk with us at http://brlcad.zulipchat.com

OpenCL GPGPU Spatial Partitioning Raytracing: We use a Bounding Volume Hierarchy (BVH) to reduce the amount of intersections we need to compute to render an image. We need to replace this with a Kd-tree in order to be able to early terminate a render in models with high depth complexity. This should speed up render speed significantly for those models (e.g. Goliath).

OpenCL GPGPU Brep Raytracing: We need to support Brep NURBS raytracing over the GPU. There is example CPU only code. Execution on the GPU should significantly enhance rendering performance of these primitives.

Open Channel For Goods Using Optics +robotics concept:
We can Create A Tunnel Like way Where we can transport goods like We Transport data through seas Using Optics. Only Need Is To make it automated with perfect coding for destination. We can Do this with the help of Software+Mechanical Engineers. Where coding and assembly plays important role..
Coding can Be Done In General By C/c++ language which is Simpler

LibreCAD is a free Open Source CAD application for Windows, Apple and Linux. Support and documentation is free from our large, dedicated community of users, contributors and developers.
Please refer to LibreCAD GSoC 2018 ideas for more detailed description.

STEP Coverage Test: Write a program that links against STEPcode and generates a STEP output instantiating every entity for a given schema. Goal is a comprehensive program and data file for testing STEP import/export.

STEP Source Code Documentation: We already use doxygen, but could do much better. Improve code documentation and utilize additional doxygen features such as topic pages. Add a 'make doxygen' target to invoke doxygen.

STEP Viewer: STEP is a common CAD file format supported by just about every major CAD system. Given we have an importer and an interface for displaying geometry, a stand-alone STEP file viewer has some great potential.

Port the GUI to C++: The GUI is currently coded in Perl using wxWidgets and our goal is to have it ported to C++. The wxWidgets API is almost identical between Perl and C++, so it's an easy task. There are a couple things where we use the dynamic features of Perl which are trickier and interesting to port.

Fix bugs of the Boost.Voronoi library: The good but unmaintained Boost.Voronoi library has a couple minor issues affecting Slic3r's results. Interesting task for learning the Voronoi algorithm and how to troubleshoot a computational geometry issue. #2948

Refactor the TriangleMesh class and support non-solid walls: Replace the internal mesh representation (currently based on admesh) using an existing 3D mesh library or implementing a half-edge structure; only use admesh for fixing models. Keep non-solid walls and slice them as single paths. Bonus: import SVG paths and position them freely using the GUI for printing as single extrusions. #3560#3523

Write a Slic3r plugin for Grasshopper: Expose Slic3r functionality as many separate components that can be plugged in larger GH definitions (for example: slice a NURBS model in GH and feed the slices to the toolpath generation process in order to skip mesh generation, or provide flow calculation for people driving 5-axis robots with custom motion). This requires a fair amount of design work.

GSoC Path/Robot Integration: Path is the CNC/CAM workbench. It currently lacks any simulation capability. Robot workbench is a tool for simulating industrial robots. Extend Path and Robot workbenches to support simulation of CNC operations in the Robot workbench.

BRL-CAD operates under group mentorship. That means you can contact anyone, not just the person assigned to you, for assistance. The mailing list and IRC channel are the preferred communication methods.
